Series overview
WHAC4532A signal line common mode chokes use the 4532 body, a size up from the WHAC3225B and WH2012 chokes, for buses that need strong common mode suppression or headroom on the pair. They are also searched as 4532 common mode chokes, common mode inductors or CAN bus common mode chokes. The table mixes U-coded parts such as WHAC-4532A-510U0, specified by inductance, with T-coded parts such as WHAC-4532A-102T0, specified by typical impedance.
WHAC-4532A-110U0, WHAC-4532A-220U0, WHAC-4532A-510U0 and WHAC-4532A-101U0 carry inductance and leakage inductance in the selector, the style of choke used on CAN and RS-485 buses. Pick the grade from the failing band and the bus rate.
Parts from WHAC-4532A-900T0 up to WHAC-4532A-142T0 are listed by typical impedance with a tolerance. Use them where the 4532 body gives needed headroom; take rated current and DC resistance from each datasheet.
WHLC-4532A-142T0 sits in the same table under the WHLC prefix, next to WHAC-4532A-142T0 with the same grade code. They are separate part numbers with separate datasheets, so compare both before choosing.
The U codes repeat in the smaller 3225 size on the WHAC3225B page, for example WHAC-3225B-110U0 and WHAC3225B510U0. If board area is tight, compare those first; codes match, but datasheets, footprints and ratings do not.
Applications
The 4532 size suits long cables, strong noise or pairs that carry more than data.
CAN harnesses in machinery, charging equipment and energy storage pick up strong common mode noise. A 4532 choke such as WHAC-4532A-510U0 or WHAC-4532A-101U0 at the transceiver adds suppression; verify timing on the harness.
RS-485 lines in factories, solar plants and building systems run long distances past motors and inverters. A U-coded part such as WHAC-4532A-220U0 at the terminal block adds suppression; recheck termination and failsafe bias.
Some buses send supply current over the data pair. For those, compare the rated current of the 4532-size parts in their datasheets, including T-coded parts such as WHAC-4532A-421T0, before you fix the footprint.

Send the part number and datasheet of the 4532 choke you use today. Our FAE team compares inductance or impedance, DC resistance, rated current and footprint, then suggests WHAC4532A candidates to validate with samples before production.
VOOHU is ISO 9001 and ISO 14001 certified. Since 2018 VOOHU has supplied more than 1,500 customers, including 150+ listed companies. VOOHU’s power line common mode chokes come from the same Mianyang magnetics factory as these parts.
FAQ
Supply, U-coded versus T-coded parts, and signal versus power line chokes.
When the failing band sits low enough to demand high impedance, or when the pair carries enough current that smaller parts run short of headroom. Both are real reasons. Board area rarely is, so confirm one of them applies before accepting the larger footprint.
A larger body forces the two traces further apart through the part, which can disturb the pair's impedance and symmetry. Follow the recommended land pattern, keep the legs equal in length, and verify differential impedance and return loss after the change.
It does when the differential pair also carries bias or supply current, which happens on some bus and power-over-data designs. Read the rated current as a maximum under stated conditions, and derate for ambient temperature and restricted airflow in the enclosure.
No. More core material generally moves the impedance peak toward lower frequencies, so a large part can perform worse at a high failing frequency. It also has more effect on a fast signal. Match the curve to your band rather than defaulting to the biggest.
With a complete part number, send the part number, quantity, delivery region and the date you need it. If you are still selecting, send the interface, the data rate, the frequency band where your scan fails and whether the pair carries current.
Yes. VOOHU manufactures WHAC4532A signal line common mode chokes in its own magnetics factory in Mianyang, China, alongside its 3225 and 2012 signal line chokes. Every part number in this selector, including WHLC-4532A-142T0, comes from that factory.
Pick a U-coded part, such as WHAC-4532A-510U0, when you design to an inductance target, as many CAN and RS-485 designs do; pick a T-coded part, such as WHAC-4532A-801T0, for an impedance target at the failing frequency.
No. WHAC4532A parts are signal line chokes for differential pairs; power line chokes filter supply inputs and are covered on the power line common mode choke pages. If one pair carries both data and supply current, ask our FAE team.
